Applicati0n MarchlB, 1947,: Se'rial No.'734,'3 50 (Cl. fill-n52) 6 Glairns. '1 "The present invention relates to a table construction, and particularly to a, construction for a table which may be used as an occasional table or as a table for utilitarian use, as, for example, a dining table. More particularly still, the invention comprehends a table of the type commonly known as'Peinbroke and in which a leaf or like element is arranged at right angles to the table top and ordinarily is positioned against a side wall of a room, the table being convertible to one in which the normally upstanding leaf is arranged in the same plane withthe horizontal leaf, either with or without an interposed additional leaf to form a table having a large surface andwhich may be utilized for dining or other utilitarian purposes.

' 'It is an object ofthe invention to provide an occasional table which may be easily and readily converted to a table for utilitarian use, having a much larger working surface than When in use as a decorative piece of furniture.

It is another object of .the invention to provide such a table in which the conversion from one form. to the other may be very simply and readily accomplished.

It is a further object of the invention to provide a table of the class previously mentioned in which an additional leaf may be inserted in order to further enlarge the table.

It is a still further object of the invention to provide such a table which is simple in construction and which may be readily and economically manufactured.

.;Other objects and features of the invention will appear when the following description is considered in connection with the annexed drawings, in which Fig. 1 is a perspective view of the table of the present invention arranged to simulate a Pembroke table;

Fig. 2 is a similar perspective view showing the table in its second form and having a much enlarged surface area; in Fig. 2 the two table leaves are shown separated in order to indicate that a separate leaf may be inserted to further-enlarge the surface area;

Fig. 3 isa fragmentary perspective view of a portion of the bottom of the table showing the meanslby which the horizontal leaf of the table may be rotated when converting the table from the form of Fig. 1 to that of Fig. 2, or vice versa;

Fig; 9 is an enlarged vertical cross-sectional view *of the table when arranged as in'Figs; 1 and 5, the section being taken on'the, plane of;the. line 9-9 of Fig. 5; and

Fig. '10 is afragmentarycross-sectional View of the upright-leaf of the table of Fig.1 1 showing particularly the mode for adapting this 'leaf' for support upon the frarne-work; this view, is taken onthe planeof the line=HJ--l0 of Fig. 9.

-Referring now tothedrawings, the table :as shown in Fig. 1 is arranged to have a horizontal surface-orleaf I I] and a vertical surface or leaf H. In this form the table-is adapted to serve as a Pembroke table, and the leaf 1 I may and ordinarily would be against a sidewall. As will be clearly indicated as'thedescription'proceeds, the leaf may-be moved -from its-vertical position and after-'rotatingthe leaf ill about a-vertical axis and relocating-it with respect to the frame- =work12 and legs I 3*, the leaf I l may be Supported upon the framework ina horizontal position, as shown in Fig. 2. As thus arranged, the parts form a :table' having alarge surface area and,-in addition. a separateleaf may be provided and may be inserted between the leaves Ill and llfor'f-urther 29- whichpass through holes-inthe inner rails 14 corresponding to holes in the upper extensions of legs :13 andinto-blindholes in the outer rails 15.

These dowel' like portions arethen held in place Fixed to the undersurface of the leaf I are the two members I8 and 20. Member I8 is arcuate in form and extends through substantially ninety degrees. This member is provided with a tongue 2! at its outer surface which cooperates with the groove I! in the forward rail I4. Member 20 is straight, as seen in Fig. 6, and extends from the outermost end of member I8 rearwardly. This member is provided at its outer surface with a tongue 22 which cooperates with the groove I! in the rear rail I4.

As will be seen particularly by reference to Figs. 5 and 6, the leaf Ili may be rotated about a vertical axis pivoting upon the rearward corner of the member and bein guided by the arcuate form of the member I8, by which means the leaf may be shifted from the position in which it is shown in Fig. 5 to that shown in Fig, 6 in full lines and then, by additional rotation, t a position in Which the leaf I6 is at right angles to the framework I2. Subsequently thereto the leaf may be moved outwardly to the dotted line position of Fig. 6, the tongue 2'2 of member 20 and the then forward corner of the arcuate member I8 then serving to guide the leaf in its sliding movement. The sliding movement just described is limited, due to the fact that the groove H in the forward rail l4 terminates adjacent its righthand end at the point 23 of Fig. 7. Thus, at this point the arcuate member 18 strikes the groove termination indicated at 23 and prevents any further movement.

Also a peg 3! (Figure 5) is inserted in the underside of the leaf iii to act as a stop and prevent movement of leaf I I) out of register with leaf I I when the leaves are in the arrangement shown particularly in Figure l.

The leaf II is provided with dowel pins 24, as seen in Fig. 9, which dowel pins extend into the upper flattened portions of the table legs l3, the leaf at this time being between the rear rails I4 and I5. Leaf I l is provided with the tongued members '25 and 26, which members cooperate with the grooves H of the front and rear rails I4 and guide the leaf l I when it is inserted in the horizontal position to form the table structure of Fig. 2. Further, leaf I0 is provided with holes 21 into which the dowel pins 24 fit when the two leaves H and II are pushed together to form a continuous table top, as illustrated in Fig. 8. In the usual manner a separate leaf may be provided haVing dowel holes in one edge and dowel pins in the other and may be inserted between the leaves ID and H to still further enlarge the table top.

It will be seen that by my improved construction I have provided a table which may be readily converted from that form illustrated in Fig. 1 to that of Fig. 2 and have accomplished this result without utilizing any complicated mechanical means and in a manner in which it is very easy to convert the table from one of the forms to the other.

The foregoing description has been given for the purpose of illustrating a preferred form of my invention. It is to be understood, however, that modifications of the structure may be made without departing from the spirit of the invention and, consequently, I wish to be limited not by the foregoing description, which was given solely for purposes of illustration, but, on the other hand, only by the appended claims.
